1. INTRODUCTION

1.1 General

This document is valid as of Dragon PTN Release 4.3DR.

In general, FXS (=Foreign eXchange Subscriber) and FXO (=Foreign eXchange Office) gateways translate analog voice/modem/fax signals to IP packets and vice versa.

FXO: towards analog PBX (=Private Branch eXchange) or PSTN; FXS: towards analog telephones, modems or faxes.

The 8-FXS interface module (=IFM) is a VoIP module and makes the transport of analog voice through the Dragon PTN packet network possible. It will convert analog voice into SIP (=Session Initiation Protocol) and RTP messages and vice versa. The SIP messages will be packetized into MPLS-TP packets via a Voice service in HiProvision, to transport the data through the Dragon PTN network. HiProvision is the Dragon PTN management system.

The Voice service can set up connections between both analog phones and SIP elements (client, server, trunk). SIP elements can be connected to the Dragon PTN network via Ethernet IFMs (e.g. 4-GC-LW, ...). Depending on where the call handling must be done, two different modes can be selected:

Remote extension (FXO Gateway): call handling via FXO gateway to analog public or private telephone networks;

SIP-server: call handling done in dedicated external SIP server;

This IFM provides 8 ports for connecting 8 analog phones to the Dragon PTN network.

Verify the 'Dragon PTN Bandwidth Overview' manual (Ref. [100] in Table 1) to see in which node and IFM slot this IFM can be used. This IFM requires an interface adapter kit in core nodes which is not needed in aggregation nodes (see §2.1, Nodes: see Ref. [3], [3b] in Ta-ble 1).

Maximum four Voice services can be configured per 8-FXS module.

The main supported features are:

Packetizing of analog voice; 8 ports FXS (G.712 compliant); Integrated battery feed and ringing generator; DTMF Dialing; Converts analog FXS port into SIP Client; Support for G.711 a/μ law and G.729 encoding/decoding; Modem and fax compatible (no T.38); Remote Extension: FXO interworking possible via external device; Interworks with standard SIP servers; Voice service modes:

Remote extension (Routable); SIP-server (Routable);

NOTE: Routable: FXO Gateway or SIP Server can be located in an IP subnet different from the IP subnet assigned to the 8-FXS ports;

Compatible products can be found in §3.

(*) Port Configured: a port is configured when it is programmed in a Voice service and it has a created account. The account must have been created via the Voice Protocol wizard in HiProvision. (**) Register: The analog phones must have been announced or registered first to a third party FXO gateway or SIP-server. This occurs via a 'REGISTER' message. After registration, the SIP server or FXO gateway knows via which IP address and extension number the analog phones can be reached. The REGISTER message will be sent automatically by the port, every 120 seconds, after the port has been configured and loaded in HiProvision. No phone has to be connected yet to start the registration. See also §2.2.5 for more info on the Register flow.

2.1.3 RJ-45 Connector Connections and Cables

The 8-FXS module provides 8 analog voice ports via 2 RJ-45 connectors, each connector providing 4 ports. Each port provides one tip/ring pair. Connections to this IFM can be made via a connection kit that can be plugged as well in a patch panel:

8-FXS Connection Kit (order no. 942 256-400) includes: An RJ-45 drop cable (1.5m) wired out on 4*RJ-11 couplers to connect ports [1..4]; An RJ-45 drop cable (1.5m) wired out on 4*RJ-11 couplers to connect ports [5..8];

Patch panel (order no. 942 256-204): 24 ports feedthrough patch panel. The RJ-45 drop cables from the connection kit can

be plugged into this patch panel. Analog telephony RJ11 cables must be plugged into the RJ-11 couplers to connect to

the 8-FXS ports;

See the table and figures below for an overview and description of the different connections, connectors and pin assignments.

2.2 Functional Operation

2.2.1 General

An application network can be connected to the MPLS-TP Dragon PTN network via one of the 8 FXS interface ports. The 8-FXS module can interface with 8 analog telephone lines. In Figure 1 and Figure 2, a common functional setup is shown.

In Figure 8 below, a more detailed functional setup is shown. An application network interfaces the Dragon PTN node via the FXS ports on the 8-FXS module. The 8-FXS converts this traffic into Ethernet traffic on the backplane. The Central Switching Module (= CSM, see Ref. [4] in Table 1) converts this Ethernet traffic into packetized MPLS-TP and transmits it via an Ethernet IFM (e.g. 4-GC-LW) onto the Dragon PTN MPLS-TP network.

1 8


Figure 8 Detailed Functional 8-FXS Example

2.2.2 I/O with the Central Switching Module (=CSM)

The 8-FXS module receives analog voice via its front panel ports and converts this into Ethernet traffic which is forwarded to the CSM via the backplane. The CSM does all the processing on this data (synchronization, CRC checks, conversions, switching…). The CSM converts this data into MPLS-TP packets and transmits it via an Ethernet IFM (e.g. 4-GC-LW) onto the WAN. On the destination side, the same processing occurs in reverse order.

2.2.3 Voice Service: Remote Extension (FXO Gateway)

See Figure 1: connections between FXS → VoIP Gateway (=FXO-GW);

Analog phones in the Dragon PTN network are a remote extension of the public (PSTN) and/or private (PBX) telephone network. The extension is possible via a third party FXO-GW (e.g. Patton);

Analog phones are connected to an FXS interface (8-FXS module);

FXO Gateways are connected to an Ethernet interface (e.g. 4-GC-LW module);

Voice switching and telephony feature handling between all phones are performed in the PSTN or PBX;

DTMF (=Dual Tone Multi-Frequency) must be used for number dialing;

Analog speech and signaling are converted and packetized by the FXS interface and the FXO-GW towards the Dragon PTN network

To set up an entire Voice service in HiProvision (See Ref.[2Leg] in Table 1):

a. Configure a Voice service in HiProvision. A voice service requires at least one 8-FXS port and one Ethernet port (e.g. 4-GC-LW).

b. Configure a Voice Protocol in the configured Voice service. This voice protocol is necessary to configure extra/enhanced voice parameters.

NOTE: 8-FXS ports are always consumed per pair in a Voice service: port1+port2; port3+port4; port5+port6; port7+port8. So if you configure port5 in a first service e.g. Voice1, port6 can only be used in the same Voice1 service.

2.2.4 Voice Service: SIP-Server

See Figure 2: SIP elements like a SIP Phone and VoIP gateway can be registered on and handled by the SIP Server;

Analog phones are connected to an FXS interface (8-FXS module) which are registered on the SIP Server;

Voice switching and telephony feature handling for all calls are performed in the SIP Server;

Possible SIP telephony features depend on the used SIP devices and their interoperability.

To set up an entire Voice service in HiProvision (See Ref.[2Leg] in Table 1):

c. Configure a Voice service in HiProvision. A voice service requires at least one 8-FXS port and one Ethernet port (e.g. 4-GC-LW).

d. Configure a Voice Protocol in the configured Voice service. This voice protocol is necessary to configure extra/enhanced voice parameters.

NOTE: 8-FXS ports are always consumed per pair in a Voice service: port1+port2;

port3+port4; port5+port6; port7+port8. So if you configure port5 in a first service e.g. Voice1, port6 can only be used in the same Voice1 service.

2.2.5 SIP Connections

After a Voice service and Voice protocol has been configured in HiProvision, voice calls (or connections) between analog and/or SIP clients can be set up via SIP calls.

Before any SIP call is possible between end clients A and B, both A and B must register first to a SIP Server, whatever mode is used, either Remote Extension or SIP Server. A registration attempt from the 8-FXS IFM automatically occurs (every 120 seconds) when the port on which A or B is or will be connected, is configured in HiProvision. As a result of a successful registration process, A and B and their location will be known by the SIP server.

Remote Extension mode: The external FXO Gateway device acts as SIP server;

SIP Server mode: A Server PC with SIP Server software can act as SIP server;

Once the registration has been done, a voice call between A and B is possible. Basically, when A calls B, a SIP Invite message will be sent to the SIP server first, which redirects the Invite message to B. B starts ringing, picks up the phone and the Voice call has been set up. Once the voice call has been established, Real-time Transport Protocol (=RTP) is used to transport the call data.

Remote Extension mode: the RTP stream always goes through the FXO Gateway device;

SIP-Server mode: It can be configured in the SIP Server itself whether the RTP stream goes through the SIP Server. If for example the calls must be monitored or recorded, the RTP must go through the SIP server. Find below some example SIP flow examples.
